Acre was conquered by the Ottomans at the beginning of the 16th century. The governor of Galilee, Ahmed al-Jazzar, developed the town, building a fortress and markets and turning it into the 'main gateway' to Eretz Israel (Palestine).

Under the British Mandate, the fortress served as a jail, where underground fighters were imprisoned and where eight Irgun fighters went to the gallows. Acre prison was the most highly-guarded fortress in the country; surrounded by walls and encircled to the east and north by a deep moat; the sea to the west. It was located in the heart of an Arab town with no Jewish inhabitants.

This was reported toEitan Livni, the most senior Irgun prisoner, who deduced that the south wall of the prison bordered on a street or alley in the Old City. The information was conveyed by underground post to the Irgun General Headquarters, with a proposal that the wall of the oil storehouse be exploited for a break-in to rescue the Irgun inmates.

Amichai Paglin (Gidi), chief operations officer, toured Acre disguised as an Arab, and after thorough scrutiny of the area, concluded that a break-in was indeed possible. After discussions at headquarters, Livni received a letter stating that it was possible to breach the wall from outside, but that the success of the operation depended on the ability of the prisoners to reach the south wall on their own.

To that end, explosives, detonators and a fuse were smuggled into the jail by the parents of prisoners, who were permitted to bring their sons delicacies, such as jam, oil, and fruit. The explosives were smuggled in inside a can, under a thick layer of jam. A British sergeant opened the can and examined its contents. When he poked inside, he felt hard lumps (in fact gelignite), but accepted the story that the jam had not gelled properly.

The first escapee,Michael Ashbel, attached explosive charges to the locks barring the gate of the corridor, and lit the fuse. There was an explosion, and the gate blew open. The second gate was blown open in the same way, opening the route to freedom. At that moment, the second group went into action; they created an obstruction by igniting kerosene mixed with oil. The ensuing fire blocked the escape route, so that the guards could not reach it. The third group threw grenades at the guards on the roof, who fled. In the confusion created by the explosion, the gunfire and the fire, 41 prisoners made their way to freedom.

Dov Cohen fired his Bren at them, but was mowed down by a volley of 17 bullets. Zalman Lifshitz, at his side, was also killed. When the firing stopped, five of the first group of 13 escapees were dead, six injured and only two were unscathed. The survivors were returned to jail. The blocking unit, consisting ofAvshalom Haviv, Meir Nakar and Yaakov Weiss, also suffered a mishap. They did not hear the bugle signal to withdraw and stayed put when the other units had already left Acre. After a protracted battle with British soldiers, they were caught and arrested. The second blocking unit, consisting of Amnon Michaeli and Menahem Ostrowicz, also failed to hear the bugle (which signalled withdrawal) and were likewise caught by the British.
